Activist investor Bill Ackman 'hasn't backed away from his real passion - trying to take down Herbalife, the nutritional supplements company he has bet $1 billion is a pyramid scheme.'

NEW YORK (TheStreet) -- Shares of Herbalife (HLF) are down -1.81% to $63.48 after it was reported that activist investor Bill Ackman "hasn't backed away from his real passion - trying to take down Herbalife, the nutritional supplements company he has bet $1 billion is a pyramid scheme," the New York Post reports.

Next week, Ackman will unveil the results of a nearly two year probe by his Pershing Square hedge fund into Herbalife nutrition clubs, the Post said.

The findings, according to Ackman, will show how the nutrition clubs - owned and operated by Herbalife's independent distributors - perpetuate the fraud.

TheStreet Ratings team rates HERBALIFE LTD as a Buy with a ratings score of B-. TheStreet Ratings Team has this to say about their recommendation:

"We rate HERBALIFE LTD (HLF) a BUY. This is driven by a few notable strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its revenue growth, notable return on equity, solid stock price performance, good cash flow from operations and expanding profit margins. We feel these strengths outweigh the fact that the company has had sub par growth in net income."
